Whakatakotoranga Paerewa mō ngā Tīwiri

Ko ngā paerewa e whakamahia whānuitia ana ko ēnei e whai ake nei:
Paerewa ā-Motu o GB-Haina (Paerewa ā-Motu)
Paerewa ā-Motu o Amerika ANSI (Paerewa o Amerika)
DIN-Paerewa ā-Motu Tiamana (Paerewa Tiamana)
Paerewa ASME-American Society of Mīhini
JIS-Paerewa ā-Motu Hapanihi (Paerewa Hapanihi)
BSW-Paerewa ā-Motu o Peretānia

Haunga ētahi inenga taketake, pērā i te matotoru o te pane me te pane i te taha kē, ko te wāhanga tino rerekē o ngā paerewa kua whakahuatia mō ngā tīwiri ko te miro. Ko ngā miro o GB, DIN, JIS, me ētahi atu kei roto katoa i te MM (mirimita), e kiia ana ko ngā miro ine. Ko ngā miro pērā i te ANSI, ASME, kei roto i te inihi, ā, e kiia ana ko ngā miro paerewa Amerika. Haunga ngā miro ine me ngā miro Amerika, kei reira anō te paerewa BSW-Peretania, ā, ko ngā miro kei roto anō i te inihi, e mōhiotia whānuitia ana ko ngā miro Whitworth.

Ko te miro ine kei roto i te MM (mm), ā, ko tōna koki piko he 60 nekehanga. Ka inehia ngā miro Amerikana me te Imperial i roto i te inihi. Ko te koki piko o te miro Amerikana he 60 nekehanga hoki, ko te koki piko o te miro Piritana he 55 nekehanga. Nā te rerekētanga o ngā waeine ine, he rerekē hoki ngā tikanga whakaatu o ngā miro rerekē. Hei tauira, ko te M16-2X60 e tohu ana i te miro ine. Ko tōna tikanga ko te diameter ingoa o te tīwiri he 16MM, ko te pitch he 2MM, ā, ko te roa he 60MM. Ko tētahi atu tauira: ko te 1/4-20X3/4 te tikanga o te miro pūnaha Piritana. Ko tōna tikanga motuhake ko te diameter ingoa o te tīwiri he 1/4 inihi (kotahi inihi=25.4MM), e 20 ngā niho i runga i te inihi kotahi, ā, ko te roa he 3/4 inihi. Hei tāpiri, ki te hiahia koe ki te tohu i ngā tīwiri i hangaia e Amerika, ka tāpirihia te UNC me te UNF i muri i ngā tīwiri i hangaia e Piritana hei wehewehe i waenga i ngā miro matotoru i hangaia e Amerika me ngā miro pai i hangaia e Amerika.

He kamupene a Yihe Enterprise e tohunga ana ki te whakaputa i ngā tīwiri miihini ANSI i hangaia i Amerika, ngā tīwiri mīhini BS, ngā pūtu kowiri, ngā mea hanga 2BA, 3BA, 4BA; ngā tīwiri mīhini DIN i hangaia i Tiamana (DIN84/DIN963/DIN7985/DIN966/DIN964/DIN967); GB Series me ētahi atu momo hua paerewa me ngā hua kore-paerewa pērā i ngā tīwiri mīhini me ngā momo tīwiri mīhini parahi katoa.
